I'm out $120 and frankly a lot pissed off. Why can't I just find a cable to do what I need. How can I convert VHS to DVD on my G5 NON INTEL Mac? This is very frusterating and I want to jump out of a very tall building. Someone, Please help me....

Try something immediate and reliable.
My suggestion to get you out of a jam immediately,
1. Step one. Determine if your input will be RGBS out of a decoder, (rare but good). composite video or SVHS composite video right from the VHS machine to the capture card, or VHS machine to firewire or USB converter back to reencoding into the capture card.
1a. (The reasons for the different types above is what capture cards are available etc., and a particular workflow might let you drop in a camera and prism scanner for film or a camera rescanning from a monitor if you have to transfer off a terribly burned VHS. Usually it is just the composite video or SVHS into the cheap-o capture card.
2. Good, now you can use your cheap-o capture card to fire into a PC computer run on either the cheap-o card`s original software and maybe Windows 2000 and a Yamaha/ESS or Creative sound card, or use Ubuntu Studio 9.10 or 10.10 with the exact same hardware and the optional advantage of editing. Ubuntu Studio happens to be really terrific at burning DVDs using the just about failing DVD burners of that we often have some around. By the way, when installing Ubuntu Studio there`s a place in the middle of the hour`s install where it asks you if you want to install,
11. 2D, 3D (Sounds like publishing, maybe not.).
22. (Something I forget.) Answer, No!
33. LADSPA horror audio. Answer, No!
44. Audio Video editing. (Audio only Sound Recorder? I forget.) Answer, yes!
3. Now you`re out of the jam. You can now concentrate on if your Hackintosh G5 will accept An AJA Kona LH family or BlackMagic DeckLink family card etc without losing your shirt during the next weeks. Next questions still here on the Cow. One trouble is that the manufacturers obviously make and sell too few of these cards. I can`t figure out a good logic why.

Oh, I`m blind. Ben, I thought I had read that you were using a non- Mac Mac. Nonetheless the answer`s at least partly the same. Grabbing camera shots on a regular PC and a regular card is amongst your options, with burning a disk or memory stick to transfer it to the G5 for editing, is typical.

Ben, one of the closest or best things to your Mac PPC and price would be a BlackMagic Decklink and cables. Seems to me that the Intensity made before the Intensity Pro but still sold new will pop into your G5 (and would work standard definition all the way down to a G3, a G2 has a built in card!). Get the card new with it`s cables and don`t bother getting a used one for $189 instead of $199. The Intensity Pro is the same card except it has one of those PCIe x 1 slots on the bottom which is slower than some PCI slots, and which your Mac G5 doesn`t have. Your other card and cable will have to go on the shelf. They are not for a Mac. -Sorry for the stern news!
